Negative, especially not in the context of what we're talking about. Literally, an entire career perception is hinged on a single playoff run. A pretty unremarkable one at that. Well, it was remarkable for its pronounced ups and downs. That's why I maintain that it's dangerous territory to start anointing players after two, non-consecutive (no less) seasons of play. It was a slippery slope then and shortly thereafter my fears were confirmed.

The lowest save percentage Thomas had in a series was 0.916. Let's compare that to other "lowest" series for recent Smythe winners:

I don't see how Thomas' playoffs can be considered to be remarkably up-and-down (besides, what you're essentially doing is reducing an already small sample size to something even smaller). Quick is really a massive anomaly with regards to how stable his save percentage was between series.
